1, on the surface of the flatness of the higher requirements to ensure that artificial grass surface layer thickness, uniform elasticity. Flatness pass rate of 95% or more,
5m ruler error 3MM, slope: horizontal 8 ‰, vertical 5 ‰, semi-circular area 5 ‰, the surface should be flat and smooth, to ensure drainage.
2, the basis should have a certain intensity and stability.
3, the surface is uniform and solid, no cracks, no bad side mahjong, the joints straight and smooth, with about 6000mm × 6000mm cut as well.
4, cushion compaction, compaction greater than 95%, after the pressure in the medium-sized roller compaction, no significant wheel tracks, no loose soil, waves and so on.
5, the cement foundation must have a water-impermeable layer, water-proof layer of new PVC thick waterproof membrane, the junction should be greater than 300mm, edge margin greater than 150mm.
6, need to consider leaving expansion joints, the width of 5 mm.
7, the basic maintenance period of 2-3 weeks.
